Title: Apparatus for processing time duration signals
IPC: H03K3/033
Filed: 1972-10-24
Abstract: 1392247 Transistor pulse circuits GENERAL SIGNAL CORP 24 Oct 1972 [3 Jan 1972] 48956/72 Heading G4H [Also in Division H3] The invention relates to an improvement in the pulse processing circuit of Specification 1,391,532. The end of a pulse at 15 (a, Fig. 2, not shown, at time Tb), which is obscured by contact bounce is detected by two monostables 35, 11. The first monostable 35 generates a pulse (b) at 23 lasting at least as long as the contact bounce is expected to last, and the second 11 generates a pulse (f) at 25 only of the pulse b of the first monostable coincides with a low voltage level at 24 (e) which indicates that the input pulse (a) at 15, and its contact bounce, have ended. The resulting pulse (f) shifts the contents of a binary counter 19 to a register 21 and resets the counter via 27, the counter 19 having counted clock pulses gated at 18 by the noisy pulse at 15. In operation, the first positive-going edge of the contact bounce signal at 15 (a, T1 or T3), causes NOR gate output 36 to go low for a period (T1-T2 or T3-T4) determined by the RC 42, 41 feedback of NOR gate 37. The positive edge at the end of this period is differentiated (c) and makes the output of NOR gate 26 low. Input 24 of monostable 11 is also held low at time T4 by an investor 43 since point 15 is high indicating that the pulse has ended. NOR 27 then responds to the two low inputs to give a high output for a period determined by R32, C33 (T4-T5). Alternative configurations for the monostable 11 have the RC feedback at the output of gate 26 instead of gate 27 (Figs. 3, 4, not shown), or use NAND gates (Figs. 4, 5, not shown).

Abstract: NH3, H2S and HCN are removed from coke oven gas by washing the gas with an aqueous solution of pickling solution salt, i.e. FeSO4-7H2O, and then passing the gas over a purification mass, e.g. bog iron ore or Luxmasse.  The crude gas may be cooled to 20 DEG  to 30 DEG  C. and tar and tar oils removed from the condensate which is then used for the washing solution, the gas being washed cold, or the gas may be otherwise de-tarred prior to hot washing, and subsequently cooled prior to contacting the mass. An example is described.ALSO:In a process for removing NH3, H2S and HCN from a gas by first washing the gas with an aqueous solution of pickling solution salt (FeSO4.7H2O), the H2S reacts with the iron to form ferrous sulphide which is removed from the solution along with an insoluble iron compound formed by reaction with the HCN, to leave a solution of ammonium sulphate. The removed iron compounds are dried to a water content of 10% and roasted to produce iron oxide and gases which may be worked into sulphuric acid.  Alternatively, the iron sulphide may be decomposed with sulphuric acid, and the liberated H2S used to produce fresh sulphuric acid.  An example is described.
